A Houston divorce attorney representing Dr. Karen Gunn, who was fatally shot by her estranged husband Monday before he took his own life, said Gunn had spoken to law enforcement officers last year about her husband’s allegedly threatening behavior, but no charges were filed.

When a clinic staff member called 911, the Harris County Sheriff’s Office deputy who responded essentially told Karen Gunn, “It’s your word against his,” Myres said.

“No one else saw it,” Myres said. “Other people came to her rescue, but they didn’t see the gun. By the time police got there, he was long gone.”

A spokesman for the Harris County Sheriff’s Office said the record of the call indicated deputies responded to the scene in 2.5 minutes, by which point Graham Gunn had left.

The deputies spoke to clinic staff and left after about 30 minutes, said Deputy Thomas Gilliland, Sheriff’s Office spokesman. Gilliland said he didn’t have a record of what was said to Gunn.

Although Karen Gunn took steps to protect herself over the next six months, her husband was still able to violently end her life at her own home on West Greenvine Court in The Woodlands, authorities said.

The Dec. 13 incident at the clinic she owned was the only time Graham Gunn brought a weapon to his wife’s office, Myres said.

Within three days, the Gunns and their attorneys had submitted a binding agreement to a Montgomery County court to restrict Graham Gunn’s access to his wife and children.

Signed by both Gunns, their attorneys and the judge, the Dec. 16 court order dictated that Graham Gunn not go within 500 feet of his wife’s home, her office, their children’s school or the home of Karen Gunn’s parents, and that he not have any communication with her or the children, Myres said.

“He could have absolutely zero contact with her in any fashion,” Myres said.

To limit Karen Gunn’s potential exposure to her husband, no court hearings were scheduled in the divorce proceeding, Myres said. The divorce trial date had recently been postponed until September, she said.

“From the moment she came to my office (in November), we had fear for her physical safety,” Myres said.
